BELT-LACING MACHINE.

To all whom it may concern:

Be it known that I, JAMns K. DIAMOND, a citizen of the United ,States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain newand useful Improvements in Belt-Lacing Machines; and I do hereby declare the following to be a full, clear, and exact description-of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto machines for lacing belts and more particularly to machines for applying wire lacings of the form shown in-the drawings, and its object is to provide the devicewith means for simultaneously clenching a series of the same, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims. reference being had to the accompanying drawings in which Figure 1 isa side elevation of a device embodying my invention; Fig. 2 a detail of the same in side elevation; Fig. 3 a side elevation showing the device as it appears in operation; Fig. 4 a front elevation of the device in open position; Fig. 5 a detail in vertical section; Fig. 6 a detail in rear elevation; Fig. 7 an enlarged detail in vertical section from front to rear; and Fig.8 a detail in plan view of the staple holding mechanism.

Like numbers refer to like parts in all of the figures.

1 represents the frame or bed of the machine. 2 is a heavy pivot pin extending transversely therethrough near the middle of. the same.

3 is an anvil" to support the staples.

4: is a fixed staple holder at therear of the anvil extending upwardly above the 'plane of the anvil and slotted at regular intervals to receive the loop end of the staples. 5 is a removable -pin extending through this holder to retain the staples therein.

6 is a movable gripping bar slotted at intervals to interlnesh with the holder 4:, to engage the loops of the staples and force the same against the pin 5. This bar 6 is pivoted at 6 to swing toward and away from the staples and is engaged at the rear by plungers 10 slidable in plugs 11 in the end of spring chambers 9 in which chambers- Specification of Letters latent.

are springs 9 engaging the plungers and yieldingly forcing the same outward against the bar 6. These plunger-s are mounted in arms 8, one at each side of the machine, pivoted on the pin 2 and extending forwardly above the anvil 3 to carry a clenching bar, preferably a square bar 7 adapted to engage the staples opposite the anvil 3 and clench the same into the end of the belt. Each end of the clenching bar 7 is provided with a push pin 15 pivoted therein and having a imited swinging movement transversely of the bar. The upper end of this push pin is concave and'engaged by a convex roller 14.

mountedi'n a lever 13 pivoted near the roller to apply'pressure to the clenching bar 7.

26 are pins to engage the rollers when the same are substantially in line between the pivots of the levers 13 and the push pins 15 whereby a very great pressure is brought to bear upon the bar 7. These levers 18 are carried in a metal frame 12 pivoted on the pin 2 and this frame is connected by a contractile spring 24 with the bar 7 whereby the push pins 15 are held in contact with the rollers 14 and the vertical position. in an opening in the head of the frame 12 closed by a plug 25.

To follow up the action of the clenching bar step by step the rear of the frame 12 is provided with a pawl 16 which traverses a ratchet 17 pivoted at one end to therear of the frame 1 and extending diagonally up ward" from the pivot toward the arm 12. T 0 turn this ratchet out of the way to fully, open the device for inserting the staples and to restore it again to place, the same 1s jointed as indicated and its operation illustrated in Figs. 1 and 2. To hold the end of the belt from slipping out of place, 1 provide a pivoted support 18 of inverted U shape adapted to turn down out of the way,- and supported in operative position as in Fig. 3 by means of bolts 20 slidable 1n the frame and engaged with recesses in the support by springs 23. These bolts are provided with upwardly projecting pins by which they may be manipulated to release To retain the push pins 15 in place, I prefer to insert pivot pins 22 into the lower ends of the same, whereby they fire pivotally retained in the sockets of the bar 7 will rise toward the v frame 12 as the levers are turned toward the" The spring 2 1 is inserted In" operation, the device is first opened up as shown in Fig. 1, which gives free access to the holding means, and the staples or fasteners placed in the holder 4 and secured therein by the pin 5. The device is then closed with the plungers 10 engaging the bar 6, thus forcing the staples firmly against the pin and holdin the same in proper alinement. The clenchingbar 7 is then brought down upon the top of the staples and the pawl 16 en aged with the ratchet 17. By operating the levers 13, the clenchin bar will be forced downward with su cient power to clench or bend the staples, and by reciprocating these levers, the bar will operate to clench the staples step by step, the pawl 16 taking up the slack at each stroke of the levers until the staples are firmly ries of fasteners, upon the anvil and spacedclenched within the end of the belt, this action being best illustrated in Fig. 3. The

springs 9 maintain'a constant and' increasmg pressure upon the bar 6 and insure proper alinement of the staples whereby they will bear uniformly on the. coupling pin when the belt is in use.

What I claim is x l. A machine for applyin belt fasteners, comprising an anvil, means or holding a seapart, a clencher bar to engage the fasteners opposite the anvil, a pivoted arm inovably supporting the bar, levers pivoted in the arm to force' the bar against the fasteners, to hold the arm, the pawl. l

2. A machine for applying belt fasteners, comprising an anvil, a holder having vertical grooves at intervals, a removable pin extending through the grooves, a mgvable clamping bar having projections to enter the grooves, springs to yieldingly force the bar toward the pin a clencher bar above the anvil, and means or forcing said bar toward the anvil a pawl and a ratchet engaged by to clench the fasteners.

3. A machine for applying belt fasteners, comprising a frame or bed, an anvil supported onthe bed, a holder at the rear of the-anvil to adjust and hold fasteners upon the anvil, a vertically movable clenching bar above the anvil, a pivoted arm carrying the clencher bar, levers pivoted in; the arm to 1 force the clencher bar toward the anvil, a

port.

4:. A machine for ap lying belt fasteners,

comprising a bed or ame, an anvil supported on the frame, a holder at one side of the anvil having slots at regular intervals to receive fasteners, a removable in extending through the slots,,a 'clampin'g bar having projectlons to enter the slots and engage the fasteners, arms pivoted to the rame,

to engage the bar, a clencher bar carried by the arms and engaging'the fasteners op c site the anvil, an arm above the clencher er and pivoted to the frame, a pawl and ratchet to hold said arm, levers pivoted in the arm to force the clencher bar downward, and a spring connecting the clencher bar and the arm to raise the clencher bar.

5. A machine for; applying belt fasteners, comprising an anvil, means or holdingfasteners upon the anvil and spaced apart at regular Intervals, a clencher bar above the anvil, pivoted arms supporting the bar, a pivoted arm between said arms, a spring connecting said arm and the bar, levers pivoted in the middle arm, rollers journaled in the levers, and push pins mounted in the bar and engaged by the rollers. j

6. A machine for applying belt fasteners, comprisin an anvil, a holder at one side of the anvil having vertical grooves at intervals, a removable pin extending through said grooves, a presser bar having projections within the grooves and movable toward and away from said pin, pivoted arms provided with spring chambers, springs in the chambers, plungers projecting from the. chambers and actuated by the sprin s to engage the bar, a clencher bar carried the arms and means for forcin the clenc er bar toward the anvil to clenc the fasteners.

In testimony whereof'I aflix my signature in presence of two witnesses.
